Answer 1

Answer:

Answer:

B. Brook finished in 100 minutes, so Lamont was faster.

Step-by-step explanation:

1 hour = 60 Minutes

60 minutes + 40 minutes = 100 Minutes.

If you run and you have more minutes then someone else that means you ran for a longer time and your a little bit slower?

Answer:

3.195

Step-by-step explanation:

Answer:

To solve this equation, you need to multiply each term separately and then add them up.

3 × 1 = 3 1 × 1/10 = 1/10 9 × 1/100 = 9/100 5 × 1/1000 = 5/1000

Now we can add them all together:

3 + 1/10 + 9/100 + 5/1000 = 3 + 0.1 + 0.09 + 0.005

Simplifying the decimals, we get:

3 + 0.1 + 0.09 + 0.005 = 3.1 + 0.09 + 0.005

Adding the decimals gives:

3.1 + 0.09 + 0.005 = 3.195

Therefore, the solution to the equation is 3.195.
